(A) Users shall provide wastewater treatment as necessary to comply with this chapter, and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in this chapter within the time limitations specified by EPA, the state or the Superintendent, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated and maintained at the user's expense. Detailed plans describing the facilities and operating procedures shall be submitted to the Superintendent for review, and shall be acceptable to the Superintendent before the facilities are constructed. The review of the plans and operating procedures shall in no way relieve the user from the responsibility of modifying the facilities as necessary to produce a discharge acceptable to the city under the provisions of this chapter.
(B) Whenever deemed necessary, the Superintendent may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and any other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this chapter.
(C) The Superintendent may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
(D) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
(E) Users which operate vehicular wash facilities shall provide, operate and maintain pretreatment facilities approved by the Superintendent to control solids and preclude the discharge of toxins to the POTW.
(F) Users which operate food preparation facilities shall provide, operate and maintain pretreatment facilities approved by the Superintendent to control the discharge of greases, fats, oils and food solids to the POTW.
(G) At least once every two years, the Superintendent shall evaluate whether each significant industrial user needs an accidental discharge slug control plan. The Superintendent may require any user to develop, submit for approval and implement the plan. Alternatively, the Superintendent may develop the plan for any user. An accidental discharge/slug control plan shall address, at a minimum, the following:
(1) Description of discharge practices, including nonroutine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the Superintendent of any accidental or slug discharge as required by § 54.40; and
(4) Procedures to prevent adverse impact from any accidental or slug discharge. The procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
